Application filed. February 2, 1921. Serial No. 441,808.

To all whom it may concern:

Be it known that I, RUDOLPH E. SWAN- SUN, :1 time of the United States, residing at Riverside, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Ophthalmic Mountingg'of which the following is'a specification.

The present invention relatesto spectacle temples ofthe combinedmetal-and-nonmetallic type, and to methods of making the same, and it has for its object to provide a new and improvedtemple of the I said type that shall Ihavethe property of flexibility. 1

l Vith theabove end in view the invention consists of the improved specta 'letenr, ple and-method, of making the same here inwftcrdesc'ribed, illustrated in the acconr panying drawings and defined in the appended-claims.

In the drawings, Fig. View of a temple constructed according-to -'a preferred embodimentof the present invention. shown hinged to a lens frame;

Fig. 2 is a vie-wot ,a non-metallic. tube" adapted to be combined with a metal rod to form a temple according to ii preferred embodiment of the present: invention: Fig. 8 is a plan of a priorart metal-rod"- or core that is adapted to be combined with the non-metallic-tubc oil-Fig. 2: Fig. 4- is an elevation illustrat ng the 0 re of Fig. 3 as provided at one end with utemple end piece or hinge n'ieinber whereby the temple maybe hino ml loth-e lcns frame. the new metallic tube being shown in dotted lines: Fig. 5 is an enlarged section on lhe line 5- 5 of Fig. l. through the flattened portion til the temple: and Fig. o'is an en largcd section on the line 6-6 of Fig. 1. through the cylindrical portion of the temple.

Temples have hitherto been made of seamless tubes it) constituted of celluloid. zylonite or other pliable. non-metallic substances, in the bores llof which have been mounted reinforcing wire cores 12. Such prior-art temples. illustrated in Fig. 4, are still and unyielding.

To render the temple flexible, according to the present invention, the rod 12 is first l is a perspective face.

made flexible prior to. its aSSembIyUWith the tube 10. As the flexibility is most needed at the forward portio1r18"of the temple, it is the forward portion of the rod 12 that is endowed with flexibility.

The preferred method of rendering the forward portion of the rod .12 fiexible eisinto' flatten it, as willbe understood from Figs.

1 and 5.

The rod is thus rendered flexible in a (lirectiontransverse to-the' plane of the flattened portion. The effect of this flexibility would be lost .in part, after the rod has been mounted in the tube 10, as shown in Fig.4. To impartgreater flexibility to the completed'temple, therefore;

improvement over the stifi','unfiexible'temipies-in use at the present day. 1

In some cases, the wire maybe gold filled, while in other cases it may be of a bliss metal-thus reducing the cost of the ma terial. On the forward end of: the wire is formed or connected-a butt or joint portion' 13 which isleft extending beyond the end let of the non-metallic tube; The butt is made in the desired shape to be hinged; as at 15. to the lens frame 16.

In some instances. I employ a wire of a size suliicient tohave the buttswaged thereonend l subsequently place the body of the wire in areducing machine and draw the body portion out to a small diameter, which is passed through the bore of the tube. In other nstances, I employ a base-metal wire drawn to the desired size to be passed through the bore of the desired size 0?? cas ing. and to the base-metal core I connect by solder or otherwise the heavier butt or hinged end of the desired size and construction, and-having a precious-metal outer sur- An ophthalmic mounting is thus produced comprising a non-metallic member and a reinforcing member partly concealed by the non-metallic member, most of the concealed portion of the metal member beward ing constituted of base metal, and the surface of the unconcealed portion of the metal member being constituted of precious metal.

In both instances, before inserting the wire into the bore of thecasing, I first cover the wire with a suitable cement which is especially constructed for causing the metallic adhere to the celluloid."

After the wire has been inserted into the tube, the rear portion 17 of the composite tem le may then be bent into loop form, as il ustra-ted -in -Fig. 1, to be passed over the -ear' of' the wearer. which bending operation may be effected Without subjectin the tube to heat. The non-metallic tu e and'the metal core will together be permanently retained in any bent position, without any tendency to straighten out.

My improved temple is extremely simple and inexpensive in co-r'istruction, as v the standard or stock tubular celluloid may be em loyed for the casing, and a standard size of base metal wire may be used as a core thereby reducing the :cost of construction to the minimum.

Having thus described one illustrative embodiment of my invention and the best mode known tome for carrying out my-method,:I desire it to be understood that although specific terms are employed, they are used in a generic anddescriptive sense and not for the purpose of limitatiomthe scope of the invention being defined and limited only by the appended claims.

I claim: a

1. A spectacle temple comprising a seamless non-metallic tube and-a reinforcing rod mounted within the tube, the rear portion of the tube with the reinforcing rod'mounted therein being bent to the shape of a temple",

and the temple bein flexible at the forward portion and adapte to be hinged at the for- 2. A spectacle temple comprising a seam,- less non-metallic tube and a reinforcing rod mounted within the tube, the rear portion of the tube with the reinforcing rod mounted therein being bent to the shape of a tem Ie, the forward portion of the rod being attened to render it flexible, the forward por-,

tion. of the tube being correspondingly flattened, and the temple beingadapted to be hinged at the forward end.

3.A spectacle temple comprising a seamless non-metallic tube and a reinforcing rod mounted within the tube and having a hinge member extending forward beyond the tube, the rear portion of the tube with the reinforcing rod'mounted therein being bent to the shape of a temple, the forward portion of the rod being flattened to render it flexible, the forward portion of the tube being correspondingly flattened, and the temple being adapted to be hinged by, means of the hinge member.

' 4. The method of making a spectacle temple adapted to be hinged at the forward end that comprises mounting a reinforcing rod the forward portion of which "is flattened to render it flexible within a seamless nonmeta'llic tube, and bending the rear portion of the tube with the reinforcing rod enclosed therein to the shape of a temple' 5. The method of making a spectacle temple adapted to be hinged at the forward end that comprises mounting a reinforcing rod the forward portion of which is flattened to render it flexible within a seamless non-meof base metal, and the surface of the uncon- 90 .cealed portion of the metal member being constituted of precious metal. 7 s

7. Anophthalmic mounting comprising aseamless non-metallic tube and a reinforcing rod in th tube, most of the portion of 9 the rod within the tube being constituted of base metal, and the surface of the portion of the rod without the tube being constituted of precious metal. In testimony whereof I afiix my signature.
